In some such embodiments, the first repository may comprise event log 104. In various embodiments, the first repository of events may comprise another data storage area of data processing environment 100. In some embodiments, the first repository and the second repository may comprise the same data storage place.

In various embodiments, the combing may operate in such a manner as to commence combing at an event in an event log, or at a point in time in an event log, where a prior combing operation ended. In some embodiments, this combing method of operation may facilitate reducing or minimizing duplicative combing. In some embodiments, the combing may occur to the entire available event log. In other embodiments, the combing may occur in a different manner. In various embodiments, the combing may be facilitated via use of a filter. In some embodiments where combing may be facilitated via use of a filter, the filter may allow for combing of certain types or kinds of events. In other such embodiments, the filter may allow for combing in additional or alternative ways. In various embodiments, change event correlation may further comprise facilitating a user in configuring the filter. In some such embodiments, a user may be able to configure the filter to comb for certain types or kinds of events, while in other such embodiments, the filter may be configurable in additional or alternative ways.

In various embodiments, change detection agent 106 may facilitate definition of one or more responses upon detecting certain one or more events logged. In various embodiments, definition of one or more responses upon detecting certain one or more events logged may be otherwise facilitated. In various embodiments, the one or more responses may include a change detection scan. For example, in some embodiments where data processing device 102 comprises a router, change detection agent 106 may be configured to perform a change detection scan of data processing device 102 upon detecting certain one or more events logged. In some such embodiments, such an event may include, for example, a write command, while in other such embodiments, additional or alternative events may trigger a change detection scan. In various other embodiments, a change detection scan may be triggered upon detecting any number of designated events for various data processing devices.

In various embodiments, the one or more responses may include an automatic alert response. In various embodiments, an automatic alert response may comprise notifying a user, for example, a system administrator, of detection of the one or more events logged. In various embodiments, an automatic alert response may comprise creating a helpdesk incident. In various other embodiments, other responses may comprise an alert response upon detecting certain one or more events logged.

In various embodiments, change detection agent 106 may facilitate determining one or more users associated with the one or more correlated events. In various embodiments, change detection agent 106 may further report by supplementing the one or more correlated events of the element with the determined one or more users associated with the one or more correlated events.

In various embodiments, change detection agent 106 may facilitate designating a first subset of the plurality of events correlated with the change detected as having a higher probability of having caused the change detected than a second subset of the plurality of events. In various embodiments, the second subset may further include multiple segments, as in an example embodiment where the plurality of events correlated with the change detected are categorized into three groups, the first subset being categorized as likely to have caused the change detected, with the second subset including two segments of categorizations: (1) possibly having caused the change detected, and (2) unlikely to have caused the change detected. In various embodiments, the first subset and the second subset may comprise another number of different categorizations of probability of having caused the change detected.

In various embodiments, designating a first subset may be at least partially facilitated by use of groupings of types of events with types of changes. In some embodiments, for example, if the detected change is a changed hashing algorithm message digest of an element of data processing device 102, a write event associated with the element may be placed into the first subset of the plurality of events correlated, while a view event associated with the element may be placed in the second plurality of events correlated. In various embodiments, the designating may be at least partially facilitated by use of other groupings. In various embodiments, the designating may be at least partially facilitated by use of a historical association of events with detected changes. In some such embodiments, for example, a particular user's association with prior detected changes may increase the probability of the user's correlated events with a current detected change being placed in the first subset of the plurality of events as opposed to the second subset of the plurality of events correlated. In various other embodiments, another type of historical association of events with detected changes may be used.
